Convert CSV to JSON Online
Runs 100% in your browser — your files never leave your device.
APIs speak JSON; spreadsheets export CSV — the handoff is constant. Paste your CSV and get a clean JSON array where the header row becomes the keys of every record. Quoted fields, embedded commas, and multi-line cells are parsed by the book (RFC 4180), and the conversion runs entirely in your browser.
How it works
- 1
Paste your CSV
The first row is read as the header; every row after becomes one object.
- 2
Read the JSON
The result appears live as you paste — errors explain themselves inline.
- 3
Copy or download
One click copies the JSON; another saves it as a file.
